To all whom, it may concern:

Be it knownthat I, HENRY E. GooDELL, a citizen of the United States of America, and a resident of Greenfield,- in the county of Franklin and State of Massachusetts, have invented certain new and useful Improvements in Miter-Boxes, of which the following is a full, clear, and exact description.

This invention relates to improvements in miter-boxes, or ruiter-boards, as sometimes termed, of the general description which is characterized by the combination, with the board or base support for the stock-to be sawed for a miter, of a swinging bar carrying bodily as upward extensions vertical sawguides, means for locking the bar at any desired angle in its position across the board, together with end gages which are adjustable in a line perpendicularly across the board, so that the edge of the board or piece of stock to be sawed by being broughtthereagainst will have the mitering saw-cut made therein on the desired line angularly in exactly the required degree to its length.

The improvements are found in various particular specific and detail structural :features, combinations, arrangements, and for'- mations to the end of improving the miterbox as a whole, rendering it a high grade, convenient, eiificient, and generally satisfactory device for the use of carpenters and other woodworkers. 1

The improvements are pointed out, described, and explained in conjunction with the accompanying drawings, and nally specistituted by strap-steel, (indicated at 18 18,)

lied in theclaims.

In the drawings, Figure 1 is a plan view of the miter-box. Fig. 2 is a front elevation of the same. box inverted. Fig. 4 is substantially a transverse sectional view, on a larger scale, of the 4 miter-box as taken on the line 4 4, Fig. 1,'the line of view being in the direction of the arrow. Fig. 5 is a vertical sectional view in detail as taken on the line 5 5, Fig. 4. Fig. 6 is a cross-sectional view in detailof the adjustable and reversible end gage and of the stationary part of the ruiter-box in which it Fig. 3 is a plan view of the miter-r has its sliding engagement and showing the means for conning it in its given adjustment. Fig. 7 is an elevation as seen at the end ofthe miter-box of the parts last mentioned, the gage being by the full line shown as having a reversed position. Fig. 8 is a'horizontal crosssectional view as taken on the line 8, Fig. 5.

Similar characters of reference indicate corresponding parts in all of the views.

The main support for the miter-box is constituted by an elongated metallic skeleton frame A, which advantageously may be composed of strap-steel to form the frame of rectangular shape, the same being bent around to the form best shown in the inverted view, Fig. 3, the extremities of the strap-like metal 10 overlapping and being screwed or riveted to the metallic bar or block 12, provided with the hub or enlargement 13, having a horizontallybored hole therethrough for a pivotal connection of the swinging bar which constitutes a support for the vertically-arranged sawguides which are mounted thereon. United to and within the rectangular frame is a member 14 of semicircular form, the end lugs 15 15 of which are riveted to the'back of frame 10, l while the front middle part is likewise rigidly connected with the front of frame l0, and thelower edge of this semicircular member 14 has notches 16 16 therein arranged in radial lines from the pivot 17, from which the bar B swings, into which notches the. lockingcatch for the bar, hereinafter pointed out, may be detachably engaged. The frame, moreover, comprises, connected therewithin, parts conthe same having transverse'portions 19, back lugs 2Q, riveted to the back of the main frame, front sections 21, obliquely crossing sections 22, and the angularly and longitudinally extending lugs 23, riveted to the aforesaid block stitute the top or table of the device, the same being' secured to the frame in any suitable manner and having their edges 27 arranged at the angles of forty-five corresponding to and adjacent the aforementioned metallic portions 22 within and strengthening the frame. Screw-eyes 28, the screw-Shanks of which are horizontally engaged in screw-threaded perforations therefor in the strap-formed frame members, receive through the eyes thereof screws 29, the shanks of which screws engage into the boards C C from below, the eye-rings serving as countersunk socketed members into which the heads of the screws are bottomed.

Having described at some length the structure of the supporting-frame,the different portions of the miter-box will be pointed out by reference characters and thereafter described 4D represents the miter-box back.

E' E represent the saw-guides, mounted on and bodily movable as one with the swinging radius-bar B aforementioned.

F represents the catch or stop device for the bar B, operative when swung and set to hold the saw-guides at any predetermined angle relatively to the general longitudinal line of thev miter-box.

Gr indicates a bar supported above and from the swinging bar B and bodily movable in unison therewith to have its position with its top edge in the plane of the board-sections of the miter-box and to constitute a direct support Y under the stock or ypiece to be sawed along the sawing-line.

H indicates the device for locking and holding the bars B and Gr absolutely rigid and immovable at any angle at which they may be set.

J'J represent the end gage-posts, which are adjustable on slides, which'latter may be endwise reversed in the slideways therefor for the purpose hereinafter explained.

The miter-box back D is constituted by two plates of steel having corrugations 30, as

shown,- suchplates being screwed rigidly to the backof the main frame and rising thereabov'eand by reason of the corrugations, as evident in theplan vview Fig. l, there are series off-apertures 32 formed, which lead downwardly at the back of the board for the escape of sawdust thereat. The inner ends of the back plates are slightly separated to give free play to the saw.

1 The saw-guides (designated by the general letters E E) are constituted, as shown in Figs.

4 and 5, more particularly by tubular posts 33 33, upwardly open and having the slot 34 through each longitudinally in the plane of its axis, and the lower extremities of these tubular posts are necked down and screwthreaded, as indicated at 39, and screw-engaged into tapped sockets therefor in the opposite extremities of the swinging bar B. rEhe saw-guides, furthermore, comprise the stems 36 36, having' enlarged heads 37 with apertures 38 to fit the saw-back, (represented at .r in Fig. 2,) said apertures 38 being continued in downward longitudinal slots 40, in which and the slots 34 the blade of the saw may be freely accommodated to have its back and forth movements in working'and as guided by the saw-guide. The slotted stems 36 have centrally and longitudinally within the slots 40 the approached ribs 42, as shown in Fig. 8, to give the closest possible guiding-bearing to the saw-blade with a minimum of friction-producing surface. In order that the stem comprising portions of the saw-guide may be vertically adjusted within a comparatively slight range, so that the blade of the saw may Work with its teeth at the completion of sawing through the piece of wood quite closely down to but without coming against the bar G, the stems are at their bottoms axially socketed and tapped, receiving screw-plugs 45 therein, which by being turned may be distended or further inclosed within the bases of the stems, and the lower ends of these screw-plugs rest on cross-pins 46, transversely penetrating the hollow base portions of the tubular posts, as shown in Fig. 4. The saw engaged through the saw-guides in the manner indicated in Fig. 2 is, with the guides, properly elevated at the commencement of a sawing action, the saw and stems 36 36 bodily rising relatively to the slotted posts 33 33 and gradually settling down therewithin as the miter sawing progresses. By turning the screwplugs 45 inwardly relatively to the bottoms of the tubular stems 36 the portions of the saw-guides, which have the capabilities for the rising and lowering movements, may have their final rests on the stops 46 to permit the teeth of the saw to come to a lower line at the completion of the miter-sawing action than if the screw-plugs were distended, it being understood that the screw-plugs are most distended when the saw is new and the blade thereof wide, the adjustments being accomplished corresponding to the wearing 52, said parts 50 and 52 being engagedby a slide tongue and way, as indicated at 53 in Fig. 5, one of the sections having the longitudinal slot 54, through which the shank of the headed screw 55 is passed and continued with a screw engagement into the other section, and when the screw 55 is screwed inwardly to its head, bearing against the adjacent bar-section, the two sections are clamped or bound together as one; but of course by loosening the screw vto the basic line of the miter-boX-for instance,

at five, fifteen, twenty, and thirty degreesH in any of which the catch-lever F may engage' as the radius-bar is swung around to bring and set the saw-guides to and at the desired line corresponding to the angle of the miter to be sawed. The limits of the swing of the bar are oppositely to angles of forty-five degrees. The catch-lever F is pivoted, as indicated at 56, to the main section 50 of the radius-bar, the inner extremity of this lever having the upwardly-extending engagement-lug 57, adjacent the vnotched edge of the aforesaid member 14` In order that when the radius-bar is forwardly distended, as and for the purpose before explained, the handle or operating end of the lever may be correspondingly distended to be at all times conveniently accessible to be operated, the catch-lever is made in-sections, the eXtensible section 58 being of dovetailed shape crosssectionally and fittedto slide in the main section 59 of the catch-lever, which main section is pivoted to the main section 50 of the radiusbar. The said distensible section of the catchlever has the upstanding pin 60, which protrudes Land engages upwardly through a vertical socket 62 in the distensible member 52 of the radius-bar, so that notwithstanding the fact that the catch -lever is fulcrulned, as pointed out at 56, to the main section 50 of the radius-bar the portion of the catch-lever Y which receives the finger-pressure whereby it is operated is compelled to have outward and inward movements in unison with the distensible radius-bar member 52.

.v The bar Gr, between the two saw-guides E E and in line therewith, having the longitudinal 'groove in such line at its upper side, is supported on the pillars 65 65, which are rigidly y secured to the main section 50 of the radiusbar and to the said bar G. There is an intermediate inverted stud 66A between the two bars, the same being rigidly united to the top' in the member 50, and said shaft 68 has thev handle-lever for conveniently rotating it. turning the handle-lever to the right the screw-threaded shaft 68 by being relatively drawn into the threaded socket 67 in the pillar has, in effect, the action to draw the stud 66 in a downward direction, drawing the bar G downwardly at its middle to a hard and firm bind against the upper edge ofthe frame 10, so that the radius-bar and the saw-guides thereon will be firmly and reliably held in any given set position and until the small shaft 68v is turned to the leftward to terminate theA bind, whereupon, of course, the 'radius-bar whenthe catch-lever is swung against its spring 61 to free the catch-lug 57 from the notches 16 may be changed to any different desired angle.

At the ends of the ruiter-box frame transverse horizontal dovetail bars 7() are firmly screwed, the bases thereof having slots 72 therein. to render the portion thereof outside of each slot flexible. Bars 7 2 are fitted to slide in the dovetail ways, the gage-post J being mounted and standing vertically upon each of the slide-bars, near the end thereof. The thumb-screw 73 has the shank thereof passed loosely through the member 7 4 at the base of the bar 70, having the dovetail slideway therein, and with a screw-thread engagement in the opposite member 75, so that by setting up the -thumb-screw the intermediate portion of the grooved bar is pinched to bind and hold the slide-bar carrying the gagepost in any given set position.

Either or both of the gage-posts may be set forwardly from the plane of the bach of the miter-boX, so that the edge of the strip to be sawed, having one portion resting thereon and its end set against the back, may be sawed at any desired unusual angle not determined .by the set-notches 16. Generally the gage- IOO IIO

miter-boX shown and described is such that steel may be largely employed for constituting nearly all of the parts, and the miter-boX is rendered available for accurate work .in any mitering that may be necessary, while the cost of the device beyond that of less efficient miter-boXes is not greatly increased.
